Jesus says don't confuse greater suffering with greater sinfulness, but to see that the whole world is fragile.
Jesus says don't confuse present safety with future security, but see we are all accountable.
In response to this, repent, because true safety is found in repentance.
Repent or Perish
13:1 There were some present at that very time who told him about the Galileans whose blood Pilate had mingled with their sacrifices. 2 And he answered them, “Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered in this way? 3 No, I tell you; but unless you repent, you will all likewise perish. 4 Or those eighteen on whom the tower in Siloam fell and killed them: do you think that they were worse offenders than all the others who lived in Jerusalem? 5 No, I tell you; but unless you repent, you will all likewise perish.”
The Parable of the Barren Fig Tree
6 And he told this parable: “A man had a fig tree planted in his vineyard, and he came seeking fruit on it and found none. 7 And he said to the vinedresser, ‘Look, for three years now I have come seeking fruit on this fig tree, and I find none. Cut it down. Why should it use up the ground?’ 8 And he answered him, ‘Sir, let it alone this year also, until I dig around it and put on manure. (ESV)
